Cristiano Ronaldo might now be one of the most exalted and celebrated footballers on the planet, one of the biggest personalities in the game, but life hasn't always been so glamorous for him.

Just like any footballer, the Real Madrid superstar was once a humble young prospect - a teenage prodigy with plenty of potential and little experience. In his early days at Manchester United , he had very different duties on the pitch to those he has now.

Helping to coach the younger kids at the club, for example. That's not an insignificant job, of course. In fact, some of those kids would go on to become first team fixtures of the future - a very young Jesse Lingard amongst them.

While the 22-year-old midfielder started United's Champions League match with CSKA Moscow this week and put in a very creditable performance, it wasn't so long ago that he was a little lad playing close attention to Cristiano's tutelage. This throwback clip shows a fledgling CR7 helping to guide little Jesse's approach to the game - he gives him some insightful pointers in the process.

That's the trick to becoming a serious young talent, then - just get coached by Cristiano.
